Re: VLF: EbNaut at 8270.003

Hello VLF,

Thanks Paul and Stefan for your RX efforts.

Here, despite the quite good antenna current, my ERP is only about 15uW (or little more).

Now is running the 1600 - 0000 UTC transmission with about 600mA (last night I was on air with 90% HR, now only 60% with a partly cloudy sky).

GE & 73

Hello Riccardo,

Thanks for your transmissions. It feels like a long time ago that i've decoded something at VLF.
Good choice to reduce the CRC by 1.
I found that the maximum list length of the EbNaut windows decoder is 2E7 :-)

Here i'm getting only one decode, '+N', which is most likely false. The QRN is very high but i did expect an easy decode anyway, strange. Also no decode from Cumiana, does it maybe mean that the QRN is stronger here in the south so we get no decode despite the lower distance? I even tried to stack the first two messages (CRC28) with no better results...

Quite a challenge. I'll continue to try...

73, Stefan

Hi VLF,

I have only reduced the CRC.

Thanks for reports, as usual...

All the best
